Yes, Earth functions as a giant magnet due to its molten iron core, which generates a magnetic field through the dynamo effect. This magnetic field extends into space, forming the magnetosphere, which helps protect the planet from solar wind and cosmic radiation. The orientation of Earth's magnetic field also plays a crucial role in navigation for various species and human-made technologies.
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
Core
Increase voltage. Increase the number of windings,
Aluminum is not magnetic, it is not effected by Electro Magnetism.
You would usually use a magnet, which is just called using a magnet.
An electro magnet proves that Electricity and Magnetism always co-exist in nature
An electro-magnet can be turned on and off.

Its an electro-magnet - currents flowing through the iron core.
A electro magnet is used for lifting things by the magnetic force provided by the amount of coils and the size of the battery

An electro magnet!
Electro-Magnet
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)
A compass works by aligning itself with Earth's magnetic field, allowing users to determine the direction of north.
An electro-magnet would be the strongest magnet. Or the sun itself would be the strongest natural magnet.
Put a magnet into AC electricity
